I want to fetch data(the images in each post) stored in https://www.instagram.com/explore/tags/selfie/?__a=1, but all I get when I decode and var_dump this is NULL.
$obj = json_decode("https://www.instagram.com/explore/tags/selfie/?__a=1", true);
var_dump($obj);
Before decoding json you have to first fetch api response.
$obj = json_decode(file_get_contents("https://www.instagram.com/explore/tags/selfie/?__a=1"), true);
You're trying to json_decode the STRING
https://www.instagram.com/explore/tags/selfie/?__a=1
What you need to do is to fetch the URL first. I suggest using file_get_contents, which takes a URL and returns the contents at the end of that URL.
Try this:
$json = file_get_contents("https://www.instagram.com/explore/tags/selfie/?__a=1");
$obj = json_decode($json, true);
var_dump($obj);
The argument to the function json_decode(), $html must be plaintext/string.
This should work.
$url = "https://www.instagram.com/explore/tags/selfie/?__a=1";
$html = file_get_contents($url);
$obj = json_decode($html,true);
var_dump($obj);

I am trying to access the value for one of the currencies (e.g. GBP) within the "rates" object of the following JSON file:
JSON file:
{
"success":true,
"timestamp":1430594775,
"rates":{
"AUD":1.273862,
"CAD":1.215036,
"CHF":0.932539,
"CNY":6.186694,
"EUR":0.893003,
"GBP":0.66046,
"HKD":7.751997,
"JPY":120.1098,
"SGD":1.329717
}
}
This was my approach:
PHP (CURL):
$url = ...
// initialize CURL:
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// get the (still encoded) JSON data:
$json = curl_exec($ch);
curl_close($ch);
// store decoded JSON Response in array
$exchangeRates = (array) json_decode($json);
// access parsed json
echo $exchangeRates['rates']['GBP'];
but it did not work.
Now, when I try to access the "timestamp" value of the JSON file like this:
echo $exchangeRates['timestamp'];
it works fine.
Any ideas?
Try removing (array) in front of json_decode and adding true in second parameter
Here is the solution.
$exchangeRates = (array) json_decode($json,TRUE);

What all you have to do is use the second parameter of json_decode function.
This is the complete code snippet.
<?php
$json='{
"success":true,
"timestamp":1430594775,
"rates":{
"AUD":1.273862,
"CAD":1.215036,
"CHF":0.932539,
"CNY":6.186694,
"EUR":0.893003,
"GBP":0.66046,
"HKD":7.751997,
"JPY":120.1098,
"SGD":1.329717
}
}';
$exchangeRates = (array) json_decode($json,TRUE);
echo $exchangeRates["rates"]["GBP"];
?>
I'm trying to get data onto my website by parsing data from a JSON format. The URL is http://api.bfhstats.com/api/onlinePlayers and I'm trying to output for example the currently players online on PC.
Here's the current code I have:
<?$json = file_get_contents("http://api.bfhstats.com/api/onlinePlayers");
$data = json_decode($jsondata, true);
echo $data->pc->peak24;?>
I thought this would work, however it's not displaying anything. I am very new to parsing JSON data so if someone could explain what I'm doing wrong that would be brilliant.
change:
$data = json_decode($jsondata, true);
to
$data = json_decode($json, true);
Also, json_decode returns an array so use:
echo $data['pc']['peak24'];
to access the data.
You first call the variable $json but then use $jsondata in json_decode.
You are missing the foreach cycle to fetch the two dimensional array $data:
<?php
$json = file_get_contents("http://api.bfhstats.com/api/onlinePlayers");
$data=array();
$data = json_decode($json, true);
//print_r ($data);
foreach ($data as $pc) {
echo $pc["peak24"]."<br>";
}
?>
Check the $json and $jsondata that have different name but should be the same.
json response as below:
{"Success":true,"ErrorCode":0,"UserInformation":{"UserID":"19"}......
how do I get the UserID value by using json_decode?
I tried the below code with no luck.
$Response = json_decode($Response[2]);
echo $Response[0][0][0];
This should work:
<?php
$json = '{"Success":true, "ErrorCode":"0","UserInformation":{"UserID":"19"}}';
$response = json_decode($json, true);
echo $userId = $response["UserInformation"]["UserID"];
?>
Please check the PHP documentation of json_decode at http://php.net/json_decode
You can use object as well if you skip the second parameter of the json_decode function.
I would like to trnsform some JSON data to a php array, this is my code:
<?php
$obj1=json_decode('http://ddragon.leagueoflegends.com/cdn/3.15.5/data/en_US/champion/Aatrox.json', true);
$championname = $obj1[data][aatrox][name];
echo $championname;
?>
The problem is that i don't know how to get the data from http://ddragon.leagueoflegends.com/cdn/3.15.5/data/en_US/champion/Aatrox.json
How can i make this code work?
Try with file_get_contents() like this:
$json = file_get_contents('http://ddragon.leagueoflegends.com/cdn/3.15.5/data/en_US/champion/Aatrox.json');
$obj1 = json_decode($json , true);
$championname = $obj1['data']['aatrox']['name'];
echo $championname;
Use file_get_contents to download a file.
$json = file_get_contents('http://ddragon.leagueoflegends.com/cdn/3.15.5/data/en_US/champion/Aatrox.json');
$obj1 = json_decode($json, true);
I'm trying to turn a JSON file of Xbox Live data into variables that I can use in a PHP generated image. My JSON file is here: http://www.xboxgamercard.org/gamercard/test3/xbox.php
I have tried this:
$request_url = 'xbox.php';
$json = file_get_contents($request_url);
$decode = json_decode($json, true);
var_dump($decode['gamertag'][0]);
but it just returns NULL.
I would like to use the JSON as shown here:
$gamertag = $data['Gamertag'];
echo $gamertag;
You need to add the full url eg:
<?php
$request_url = 'http://www.xboxgamercard.org/gamercard/test3/xbox.php';
$json = file_get_contents($request_url);
$data = json_decode($json, true);
//Example output
echo $data['gamertag']; //Crylics
echo $data['gamerscore']; //7492
/* Too access the recent_games key you will need
to loop through it or access it like
*/
echo $data['recent_games'][1]['title']; //Call of Duty: WaW
?>
